Merge the supplemental font data files used with XFA documents When XFA support was added, the size of the *built* `pdf.worker.js` file increased quite a bit. Hence I think that it makes sense to, where easily possible, do what we can to (slightly) reduce the size of the PDF.js library. The supplemental font data files (added for XFA rendering), containing rescale-factors respectively widths, seem like an excellent candidate here since they're not particularly large in either line-count or file sizes. In this patch these files are instead merged into a *single* file per font, rather than four different ones, and even with these changes the resulting source files don't become all that large.[1] For e.g. the `gulp mozcentral` build, this reduces the size of the *built* `pdf.worker.js` file by more than `3 kB`. Given the overall simplicity of the patch, that kind of size decrease definitely seem worthwhile to me. --- [1] Especially when compared to truly large files such as e.g. `glyphlist.js`, `metrics.js`, and `unicode.js`.

XFA - Fix text positions (bug 1718741) - font line height is taken into account by acrobat when it isn't with masterpdfeditor: I extracted a font from a pdf, modified some ascent/descent properties thanks to ttx and the reinjected the font in the pdf: only Acrobat is taken it into account. So in this patch, line heights for some substituted fonts are added. - it seems that Acrobat is using a line height of 1.2 when the line height in the font is not enough (it's the only way I found to fix correctly bug 1718741). - don't use flex in wrapper container (which was causing an horizontal overflow in the above bug). - consequently, the above fixes introduced a lot of small regressions, so in order to see real improvements on reftests, I fixed the regressions in this patch: - replace margin by padding in some case where padding is a part of a container dimensions; - remove some flex display: some containers are wrongly sized when rendered; - set letter-spacing to 0.01px: it helps to be sure that text is not broken because of not enough width in Firefox.

XFA - Fix text positions (bug 1718741) - font line height is taken into account by acrobat when it isn't with masterpdfeditor: I extracted a font from a pdf, modified some ascent/descent properties thanks to ttx and the reinjected the font in the pdf: only Acrobat is taken it into account. So in this patch, line heights for some substituted fonts are added. - it seems that Acrobat is using a line height of 1.2 when the line height in the font is not enough (it's the only way I found to fix correctly bug 1718741). - don't use flex in wrapper container (which was causing an horizontal overflow in the above bug). - consequently, the above fixes introduced a lot of small regressions, so in order to see real improvements on reftests, I fixed the regressions in this patch: - replace margin by padding in some case where padding is a part of a container dimensions; - remove some flex display: some containers are wrongly sized when rendered; - set letter-spacing to 0.01px: it helps to be sure that text is not broken because of not enough width in Firefox.

Merge the supplemental font data files used with XFA documents When XFA support was added, the size of the *built* `pdf.worker.js` file increased quite a bit. Hence I think that it makes sense to, where easily possible, do what we can to (slightly) reduce the size of the PDF.js library. The supplemental font data files (added for XFA rendering), containing rescale-factors respectively widths, seem like an excellent candidate here since they're not particularly large in either line-count or file sizes. In this patch these files are instead merged into a *single* file per font, rather than four different ones, and even with these changes the resulting source files don't become all that large.[1] For e.g. the `gulp mozcentral` build, this reduces the size of the *built* `pdf.worker.js` file by more than `3 kB`. Given the overall simplicity of the patch, that kind of size decrease definitely seem worthwhile to me. --- [1] Especially when compared to truly large files such as e.g. `glyphlist.js`, `metrics.js`, and `unicode.js`.

XFA - Fix text positions (bug 1718741) - font line height is taken into account by acrobat when it isn't with masterpdfeditor: I extracted a font from a pdf, modified some ascent/descent properties thanks to ttx and the reinjected the font in the pdf: only Acrobat is taken it into account. So in this patch, line heights for some substituted fonts are added. - it seems that Acrobat is using a line height of 1.2 when the line height in the font is not enough (it's the only way I found to fix correctly bug 1718741). - don't use flex in wrapper container (which was causing an horizontal overflow in the above bug). - consequently, the above fixes introduced a lot of small regressions, so in order to see real improvements on reftests, I fixed the regressions in this patch: - replace margin by padding in some case where padding is a part of a container dimensions; - remove some flex display: some containers are wrongly sized when rendered; - set letter-spacing to 0.01px: it helps to be sure that text is not broken because of not enough width in Firefox.

Merge the supplemental font data files used with XFA documents When XFA support was added, the size of the *built* `pdf.worker.js` file increased quite a bit. Hence I think that it makes sense to, where easily possible, do what we can to (slightly) reduce the size of the PDF.js library. The supplemental font data files (added for XFA rendering), containing rescale-factors respectively widths, seem like an excellent candidate here since they're not particularly large in either line-count or file sizes. In this patch these files are instead merged into a *single* file per font, rather than four different ones, and even with these changes the resulting source files don't become all that large.[1] For e.g. the `gulp mozcentral` build, this reduces the size of the *built* `pdf.worker.js` file by more than `3 kB`. Given the overall simplicity of the patch, that kind of size decrease definitely seem worthwhile to me. --- [1] Especially when compared to truly large files such as e.g. `glyphlist.js`, `metrics.js`, and `unicode.js`.

XFA - Fix text positions (bug 1718741) - font line height is taken into account by acrobat when it isn't with masterpdfeditor: I extracted a font from a pdf, modified some ascent/descent properties thanks to ttx and the reinjected the font in the pdf: only Acrobat is taken it into account. So in this patch, line heights for some substituted fonts are added. - it seems that Acrobat is using a line height of 1.2 when the line height in the font is not enough (it's the only way I found to fix correctly bug 1718741). - don't use flex in wrapper container (which was causing an horizontal overflow in the above bug). - consequently, the above fixes introduced a lot of small regressions, so in order to see real improvements on reftests, I fixed the regressions in this patch: - replace margin by padding in some case where padding is a part of a container dimensions; - remove some flex display: some containers are wrongly sized when rendered; - set letter-spacing to 0.01px: it helps to be sure that text is not broken because of not enough width in Firefox.

const HelveticaRegularLineHeight = 1.2;
Merge the supplemental font data files used with XFA documents When XFA support was added, the size of the *built* `pdf.worker.js` file increased quite a bit. Hence I think that it makes sense to, where easily possible, do what we can to (slightly) reduce the size of the PDF.js library. The supplemental font data files (added for XFA rendering), containing rescale-factors respectively widths, seem like an excellent candidate here since they're not particularly large in either line-count or file sizes. In this patch these files are instead merged into a *single* file per font, rather than four different ones, and even with these changes the resulting source files don't become all that large.[1] For e.g. the `gulp mozcentral` build, this reduces the size of the *built* `pdf.worker.js` file by more than `3 kB`. Given the overall simplicity of the patch, that kind of size decrease definitely seem worthwhile to me. --- [1] Especially when compared to truly large files such as e.g. `glyphlist.js`, `metrics.js`, and `unicode.js`.
